  By the way, in such a glass plate processing apparatus, since the suction pad is raised and lowered by the air cylinder device, it is difficult to control the lifting position and the lifting speed of the suction pad. In the delivery of the glass plate on the plate support, the suction pad must always be raised and lowered with the full stroke of the air cylinder device. As a result, in the glass plate transfer device using the air cylinder device for raising and lowering the suction pad, When transferring the plate, it takes time to move up and down the suction pad, and each suction pad receives the glass plate, and the transfer to the next processing position waits for completion of the lift due to the contraction of the air cylinder device that lifts the suction pad. It takes a lot of time to start, Takes time to transport the glass plate to the working position, the improvement of productivity of machining the glass plates can not be expected.

  The present invention has been made in view of the above-mentioned points. The object of the present invention is to speed up the conveyance of a glass plate from one processing position to another processing position and to shorten the tact time of the processing operation. Therefore, an object of the present invention is to provide a glass plate processing apparatus capable of further improving the productivity of the processed glass plate.

  The glass plate processing apparatus of the present invention has a glass plate support portion for supporting a glass plate to be processed, and at least two processing positions arranged at intervals from each other, and among these at least two processing positions A conveying device that conveys the glass plate from the glass plate supporting portion at one of the processing positions to the glass plate supporting portion at the other processing position of the at least two processing positions.

The suction pad is connected to the lifting motor, and the suction pad is attached to the slider and can be lifted and lowered by the operation of the lifting motor.

  According to the present invention, since the slider crank mechanism converts the rotational movement of the crankshaft by the lifting motor into the lifting movement of the suction pad, it is necessary to rotate the crankshaft forward and backward each time the suction pad moves up and down. The crankshaft only needs to be rotated in one direction. In the slider crank mechanism, the lifting speed V of the suction pad V at the top dead center and the bottom dead center of the slider, that is, the lifting and lowering of the suction pad. V = 0, that is, at the conversion position from the ascent to the descent of the suction pad and the conversion position from the descent to the ascent, the speed becomes zero, and the speed is reduced to V = 0 (deceleration curve), and this speed V = 0 Since the acceleration (acceleration curve) is smooth, the glass plate is lifted from the glass plate support by the suction pad and the glass plate is supported by the suction pad. The glass plate support part can be placed gently, and in particular, the glass plate support part based on the adsorption of the glass plate by the adsorption pad by matching the position of the bottom dead center of the raising and lowering of the adsorption pad close to the upper surface of the glass plate support part The glass plate is lifted from the glass plate and placed on the glass plate support portion based on the suction release of the glass plate by the suction pad.

In a preferred example, a lifting device, preferably a lifting control device for transporting a glass plate from one processing position to the other processing position by simultaneously controlling a lifting motor, preferably a transport control motor for reciprocating a servo motor and a transport shuttle. When the glass plate is moved up by using an adsorbing pad and moved closer to the other processing position where the glass plate is transferred, the glass plate is lowered gradually using the lifting device. You can avoid problems such as collision and contact with other members by raising the transport height of the glass plate by suction pad during transport movement The glass plate is gradually lowered as it approaches the other processing position for placing the glass plate on the next glass plate support, and when the glass plate reaches the other processing position, the glass plate support The suction pad can be accurately positioned at the height of the minimum distance required for passing the glass plate. At this other processing position, the glass plate lowered with the minimum distance is placed on the glass plate support at the other processing position. Next, the suction pad is raised to the required minimum distance again at the same time, and at the same time, the return stroke for the empty suction pad is started, and the empty suction pad is further raised along with the start of the return stroke. As the position approaches, the empty suction pad is lowered and returned to the upper side of the glass plate support at one processing position. As a result of being able to wait until the start of the conveyance of the glass plate, the time for picking up the glass plate, the time from the lifting to the start of conveyance to the other processing position, the time from the lowering of the suction pad to the completion of the suction lifting of the glass plate In addition, it is possible to shorten the time until the start of conveyance of the received glass plate.

  Therefore, according to this invention, the conveyance time of a glass plate can be shortened, the start of the processing operation in a processing position becomes quick, and the production speed of the processed glass plate can be raised greatly.

The ascending / descending speed V of Z becomes V = 0, that is, the speed becomes 0 at the conversion position in the direction Z of the suction pad 90 from the rise to the drop and the conversion position from the drop to the rise, and the deceleration to this speed V = 0 ( Since the acceleration (acceleration curve) is smooth from this speed V = 0, the glass plate 5 is lifted by the suction pad 90 from the suction pad 90 and the glass plate by the suction pad. 5 can be gently lowered and placed on the glass plate support portions 20b, 20c, 20d and 20e, and in particular, the position of the bottom dead center of the lifting and lowering of the suction pad 90 is set to the glass plate support portions 20a, 20b, 20c. And holding the glass plate 5 from the glass plate support portions 20a, 20b, 20c and 20d based on the adsorption of the glass plate 5 by the adsorption pad 90. Lower, a glass plate support unit 20b based on releasing adsorption to the glass plate 5 by the suction pad 90, 20c, mounted to 20d and 20e is ensured.

  In the glass plate processing apparatus 1, the grinding unit 3 is configured such that the grinding head 10 and the grinding table 12 perform contour control movement in the XY coordinate system, but the grinding head 10 is fixed and the glass plate 5 is held. A contour control method in a polar coordinate system in which the grinding table 12 is rotated by angle control and moved in the Y axis may be used, and when the grinding table 12 is returned to the Y axis origin, the suction pad 90 of the lifting device 91 of the transport device 79 is used to remove the grinding unit. The glass plate 5 may be carried into and out of the grinding unit 3.

  Furthermore, the glass plate processing apparatus 1 includes the folding portion 4 between the cutting portion 2 and the grinding portion 3, but omits the folding portion 4 and cuts the breaking of the glass plate 5 at the cutting portion 2. The splitting may be performed continuously, that is, the press device 68 may be provided in the cutting head 9, and the press device 68 may perform the splitting immediately after the cutting line is formed by the cutter wheel 14. The glass plate 5 may be transported from the split cutting unit 2 to the grinding unit 3, in other words, one processing position forms a cut line on the surface of the glass plate 5 and the glass plate 5 is folded according to the cut line. The cutting part and the split part to be split, and the other processing position may be the grinding part 3 for grinding the peripheral edge of the glass plate 5.
